An event that produces multiple copies of a gene or of any sequence of DNA. Gene amplification plays a role in cancer. Amplification can occur in vivo (in the living individual) or in vitro (in the laboratory).

The production of multiple copies of a sequence of DNA. Repeated copying of a piece of DNA. DNA amplification plays a role in cancer cells. A tumor cell amplifies, or copies, DNA segments as a result of cell signals and sometimes environmental events. Amplification can occur in vivo (in the living individual) or in vitro (literally "in glass&q [..]

See gene amplification

1) In molecular diagnostics, a process by which multiple copies of genetic material (RNA, DNA) are generated so as to produce adequate levels of the target to be detected or quantitated 2) The process by which the signal from a detection system is increased so as to improve detection or quantitation of an analyte of interest, such as genes or drugs [..]

The amount of change in measured output per unit change in input. The slope of the input-output, or dose-effect, curve. (Engineers sometimes refer to “amplification” as “sensitivity”.)

Shaking levels at a site may be increased, or amplified, by focusing of seismic energy caused by the geometry of the sediment velocity structure, such as basin subsurface topography, or by surface top [..]

To increase the power or strength of a signal.

  1. Treatment (e.g., use of chloramphenicol) designed to increase the proportion of plasmid DNA relative to that of bacterial (host) DNA.

(French : amplification) An increase in the number of copies of a specific DNA fragment; can take place in vivo or in vitro. See cloning

(French : amplification d’ADN) In vivo or in vitro increase in the number of a specific DNA fragments.

Amplification is the use of substances which directly increase the amount of signal measured in proportion to the quantity of analyte.

an increase in the number of copies of a specific DNA fragment.

(n) addition of extra material or illustration or clarifying detail(n) the amount of increase in signal power or voltage or current expressed as the ratio of output to input(n) (electronics) the act o [..]

The increase of signal strength. Amplification does not improve the signal quality received but can improve the picture quality viewed on TV due to low signal strength.

the process of increasing the strength or level of a signal using an amplifier.

The art of developing ideas by finding ways to restate them in a speech.

<molecular biology> An increase in the number of copies of a specific DNA fragment, can be in vivo or in vitro. See: cloning, polymerase chain reaction. (09 Oct 1997)

Increase in number; replication. (AIHA, 1996)

Increase of the signal detected to adjust signal intensity.

a method for increasing the amplitude (or loudness) of electrical signals

process that makes electronic signals louder.

An increase in the number of copies of a specific DNA fragment; can be in vivo or in vitro.

The increase in signal level, amplitude or magnitude.

Amplification (gain) is the ratio of the strength an output signal to that of an input signal. Analog signals are amplified, digital signals are repeated.

An increasing of signal strength.

The process of increasing a signal in amplitude (as of voltage or current). The ratio of output magnitude to input magnitude in a device that is intended to produce an output that is an enlarged repro [..]

The process of obtaining an output signal greater than the input signal, through auxiliary power controlled by the input signal. The process of increasing the strength, current, power, or voltage, of [..]

Procedure of expanding the strength of a signal.

The act, or result of amplifying, enlarging, extending or adding. (physics) The act, or result of independently increasing some quantity, especially voltage, power or current. (electronics) Gain [..]
